Windows 10 not supported with Air Display, Duet display seems to only be for iPad as secondary display, Spacedesk is showing up an error every time I try to install it (5x now) "incompatible hook driver" I've contacted support and am waiting to hear back. Zonescreen is for Windows only.

Video connections on computers (any) are output only. Wish you could use the Surface as monitor sometimes. Your best solution is to purchase a nice size monitor for at home. They are a cheap way to save you vision.
